Change Order Category Structural Safety Section ( SSS ) Hassan Sassi, PE, SECB
Structural Safety Overview Q. What is DSA Looking for in Structural Safety? A. DSA considers the following: Changes that may impact the Foundation Changes that may impact the gravity system Changes that may impact the lateral (Seismic) system Anchorage of Non-Structural Components
Structural Safety Top 10 Issues 1. Changes to Structural without SEOR Approval/Knowledge 2. Calculations or SEOR Stamp and Signature 3. Foundation Changes 4. Anchorage Changes 5. Post/Column Changes 6. Beam Changes 7. Connection Changes 8. Mechanical Units 9. Soffits 10.Mounting of Non-Structural Components
1.1 Changes to Structural without SEOR Approval Q. Why is the SEOR Approval important to DSA? A. For the following reasons: SEOR s knowledge and experience. When there is a structural change, DSA is looking for an SEOR stamp and signature. Modifying a standard detail will still require an SEOR stamp and signature. Second pair of eyes for review.
1.2 Changes to Structural without SEOR Approval Missing Typical Information Without SEOR Stamp and Signature, Calculations are Required
2.1 Calculations or SEOR Stamp & Signature Basic Changes: Provide the SEOR stamp and signature. Or include calculations to justify change. Complex Changes: Require stamp, signature and calculations.
2.2 Calculations Example Case Study #1 Verify by calculations that ¾ Hilti KWIK Bolt 3 with 4 ½ embedment has the same capacity as the approved detail of ¾ A307 Headed anchorage with 6 embedment.
3.1 Foundation Changes Q. What are the most common foundation issues? A. Typical foundation issues are: Score Board Pole Foundation Light Pole Foundation Flag Poles Foundations (taller than 35 ) Stair Landing too Close to Existing Footing Canopy Pole Foundation Need to be Moved due to Interference Utility Lines or Pipes too Close to Footing
3.2 Foundation Changes Case Study #1 Piping/Conduit through Footings COs should include: Section Detail Quantity of Conduits Detailed Locations
3.3 Foundation Changes Case Study #2 Show how metal stud furring wall is connected to concrete wall (how 18 ga. angle connected to metal stud). Clarify and show how new curb is connected to slab on grade. Detail said that Anchor bolt embedment is 4" minimum into curb, but curb is 6" minimum.
4.1 Anchorage Changes Q. What are typical issues related to anchorage? A. The following are typical issues: Edge distances Embedment ICC Report Compliance with ICC Report
4.2 Anchorage Changes Case Study #1 As per IR 19-1, shallow epoxy type anchors are not allowed for overhead applications.
5.1 Post/Column Q. When a Post changes what is important? A. The following is important: SEOR is involved. Material Steel, Concrete, Masonry, Wood. Location changes may impact span lengths and loading. Size for adequacy for loading, torsion and deflection. Connection is still adequate or has changed as well. Calculations as required for any complicated change.
5.2 Post/Column Case Study #1 CO Allows Nine (9) Penetration is Load Bear Post Shear Wall
5.3 Post/Column Case Study #1 Calculations Required Spacing Between Holes Hole Sizes (7/S1.50) Loading on the Member
5.4 Post/Column Case Study #1 Detail 7/S1.50 Hole Size is 0.4d D=6 Hole = 2.4 Why is this important?
5.5 Post/Column Case Study #1 3 1.2 1.8 At the narrowest section, the wood is 1.8 thick. 8d Common nail is approximately 2.5. Penetrating the hole and whatever is inside.
6.1 Beams Q. When a beam changes what is important? A. The following is important: SEOR is involved. Material Steel, Concrete, Masonry, Wood. Location changes may impact span lengths and loading. Size for adequacy for loading, torsion and deflection. Connection is still adequate or has changed as well. Calculations as required for any complicated change.
6.2 Beams Case Study #1 Justify the removal of the W8x beam would not jeopardize the structural integrity of the opening.
6.3 Beams Case Study #2 Provide details on how the studs are attached to the metal deck and/or the steel beam.
6.4 Beams Case Study #3 Verify the location of the perpendicular beam serving as a brace is directly aligned with the Guard Rails Support. If not, SEOR should provide an acceptable tolerance/range where the beam acts as a brace. Include this dimension in the revised note.
7.1 Connections Q. When a connection changes, what is important? A. The following is important: SEOR is involved. Detailing all the components and dimensions. Material to Material Type is identified. Location(s) if the change is not applicable in all locations. ICC Reports for adequacy and proper use. Calculations as required for any complicated change.
7.2 Connections Case Study #1 Provide beam and column connections to (E) structure.
8.1 Mechanical Unit Q. When a Mechanical Unit changes, what is important? A. The following is important: SEOR is involved. Location - Roof, Wall, or on Grade. Weight of Unit to determine if the supporting structure is still adequate. Connection is still adequate or has changed as well. Calculations as required for any change.
9.1 Soffits Q. When dealing with a soffit, what is important? A. The following: SEOR is involved. Lateral Bracing for seismic load adequacy. Connection is still adequate or has changed as well. Calculations as required for any change.
9.2 Soffits Case Study #1 This one got it right! Members are Called Out Connections are Detailed ICC Report Allows Seismic Loads SEOR Stamped and Signed (No Calculations Needed)
10.1 Mounting of Non-Structural Components Q. When dealing with Non-Structural components what is important? A. The following: Weight for load adequacy. Details for attachment or mounting.
10.2 Mounting of Non-Structural Case Study #1 2x8 Blocking No Connection Details No Clear Support of the 2x8

DSA Administrative Key Issues Q. What is DSA looking for in a CO Submission? A. Compliance with IR A-6: A complete description. That it is neat and orderly. That the project information is on every page.
Guidelines, Code and Other Resources DSA IR A-6
Administrative Category Top 8 Topics 1. Type of CO 2. CO Narrative 3. Organization and Formatting 4. Typical Project Information 5. Review of Sketches for Matching Scope 6. Checking Updated Stamps 7. Additional Attachments 8. Extraneous Material
1.1 Type of CO Three (3) Types of Change Orders: No Change (5-10%) Does not change the DSA approved plans or specifications. Non-DSA Content (10-15%) Changes to the plans or specifications does not affect DSA s primary review components (ACS, FLS, or SSS). DSA Content (75-85%) Changes to the plans or specifications affects DSA s primary review components (ACS, FLS, or SSS).
1.2 Type of CO No Change General Concept - CO is for Cost or Time adjustments only. Additional labor may be attributed to Rework. Examples Time Adjustment due to weather Overtime or Fire Watch Repair or Rework Off Site Work
1.3 Type of CO No-Change Requirements: 1. Clear Stand Alone Narrative for No Change Confirmation 2. Phrase NO CHANGE TO DSA APPROVED DOCUMENTS 3. Appropriate Signatures 4. No Other Documentation
1.4 Type of CO Non-DSA Content Change: General Concept CO modifies the Approved Drawings, but does not impact DSA s primary review elements (ACS, FLS, SSS). Under the 2010 Code, DSA is interested only in changes to their primary review (ACS, FLS, or SSS). Old codes still require approval for all CO s.
1.5 Type of CO DSA Content Change: General Concept CO modifies the Approved Drawings and impact DSA s primary review elements (ACS, FLS, SSS). DSA s eye are on these CO s.
2.1 CO Narrative Q. What is DSA looking for in a narrative? A. 3 W s: Where Be as specific as possible to narrow down where the change occurs. Building, Floor, Classroom, Grid Line, etc. What Fully describe what the change entails. This allows DSA to understand before they even get to review the sketches. Why By specifying the cause of the change, DSA can now understand why the modification was required.
2.2 CO Narrative Case Study #1 Q. Where was the change? Q. What modification occurred on the wall coverings? Q. Why were they changed? A.????Where is this Construction Directive #69.2??Where is this Architectural Supplemental Information #34?

DSA Access Resources RESOURCES of the DIVISION OF THE STATE ARCHITECT For the Division of the State Architect, there is more than one way to get to the agency s on-line publications. However, some of the agency s information is only in one location and is not easily found. Therefore, for all of those involved in work related to the DSA it is recommended they periodically explore the agency s website, with its many links, in order to maintain familiarity with its information, which may be updated. In order to assist with the exploration of the DSA s publications, see the following information: DSA Home http://www.dgs.ca.gov/dsa/home.aspx DSA Publications http://www.dgs.ca.gov/dsa/resources/pubs.aspx
